	just a quick update, I have tried changing where my video card is, changed and unplugged all sata devices, re-seated the ssd multiple times, changed ram configuration, upgraded and downgraded my bios, installed the samsung ssd and intel chipset drivers, changed csm, fastboot, legacy and uefi setting, and am currently attempting this bios mod guide with little success as it seems that they aren't interested in x99 support as "all x99 boards support nvme ssds." https://winraid.level1techs.com/t/howto-get-full-nvme-support-for-all-systems-with-an-ami-uefi-bios/30901 as previously mentioned, any help or advice would be nice, although it seems like the best advice right now would be to return the ssd and never buy an asrock pos.

	If you have not already, open a support ticket with ASRock: https://tw.asrock.com/events/tsd.asp This is a community forum so the only way you get help here is from other users who may have encountered and solved similar issues. ASRock does occasionally post here but not very often and usually regarding more wide spread issues/fixes. NVMe was in it's infancy when x99 launched so it's not surprising support is somewhat limited, particularly with newer, large capacity drives. Good luck, hopefully ASRock support can help you out.
